To all, 'whom it mayooiwcrn:

Be it known that I, FREDERICK-A.' -MUEL- LER, a citizen of the United Statestresiding at Indianapolis, in the -county otfMarion and State lof Indianzulnweinvented certain new and useful Improvements in Clinker Scoops, of which the following is a specification.

My said invention relates to a clinker scoop for furnaces and stoves and it is an object of the same to provide a scoop which shall be adapted to be used with an ordinary furnace hook or poker.

A further object of the invention is to provide a device of the character described which shall be simple and inexpensive to manufacture but which shall be more etlicient in operation than devices hitherto known.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is an elevation of a furnace having parts omitted to show the operation of a furnace hook in loosening clinkers,

Figure 2, a similar view illustrating how the device of my invention cooperates with such a hook in removing a. loose clinker from the furnace,

Figure 3, a perspective of my device in position on a furnace hook, and

Figure 4, an end view of the scoop.

In the drawings reference character 10 indicates a furnace which may be of any conventional form in which clinkers occur as illustrated at 11. It has hitherto been suggested that various kinds of tongs and analogous devices be inserted through the door 12 for grasping clinkers and withdrawing them through the door but such devices have been objectionable for various reasons such as that they could not be entered through doors of certain forms or in any location except the most conventional, that they were too expensive, that they could not be manipulated .readily to engage clinkers of varying size or in different parts of the furnace and so on. These objections are overcome by the use of the device of my invention which comprises a rod 13 having at its upper end a hand grip 14 and at its lower end a scoop 15 preferably comprising a series of prongs bent forward at the lower end at 16 to cooperate with a lateral pro` 18 in gripping a clinker jection at 17 on the furnace hook or poker such as illustrated at 11 saidlateral projectionbeing ordinarily merely the bent end offthe rod 18. The "scoopfis provided at its upper end with la hook which is adapted to receive the shaft 18.

In the use of the 'device clinkers are loosened by means of the furnace hook by which means also they may be dug up out of the ashes which may be on the grate and brought into position for convenient removal. Thereafter the hook 19 is positioned on the rod 18 by lateral movement of the scoop over 18 through the opening in hook 19 as illustrated in Figure 3 all parts being so connected after they are entered in the furnace door, and not before, after which the hook can be positioned as shown in Figure 2 and the scoop can be slid along the rod or rotated about the same or tilted laterally relatively thereto with the result that a clinkcr of any form or in any position can easily be picked up and withdrawn from the furnace.

The shaft 13 may be joined to the scoop in any convenient manner preferably, however, by forming a depression in the scoop in which the end of the shaft is located and thereafter electrically welding the parts together.

It will be obvious to those skilled in the art that this method of connecting the parts may be changed as may also `other details of the invention without departing from the spirit thereof and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination of a furnace hook, a scoop having prongs movable toward and from a lateral projection of the furnace hook, and connections between the scoop and the shaft of the furnace hook whereby the scoop may have universal movement relative to the furnace hook, substantially as set forth.

2. A device for removing clinkers from furnaces comprising a furnace hook having a handle, a scoop having prongs for cooperation with said hook said scoop having a hook adapt-ed to engage the handle of said furnace hook and permit said scoop to be operated to engage a clinker7 substantially as set forth.

3. The combination of a furnace hook embodying a shaft having a bent end, and a scoop comprising a body having prongs eX- tending from one side and an additional prong extending from its opposite side, said prong forming a hook for engagement about the shaft of said furnace hook and adapted to be moved longitudinally thereof and tilted for engagement of a olinker, substantially as set forth.

4. In combination a furnace hook comprising a rod having a lateral projection at one end, al scoop comprising diverging prongs at its lower end and a hook at its uper end for engagement about said rod whereby the furnace hook and scoop may be independently inserted in a furnace and cooperatively manipulated for engaging a clinler7 substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 13th day of May, A. D. nineteen hundred and twenty-four.
